Tversky and Kahneman’s 1974 work, Judgment under Uncertainty: Heuristics and Biases, introduced three key characteristics: representativeness, anchoring and adjustment, and availability.

What is Gardner's Theory of Multiple Intelligences? However, different initial values lead to different estimates, which are in turn influenced by the initial value. We tend to assume that if several examples are readily available in our mind, the event or subject matter is commonplace. In summary, a heuristic is a mental shortcut that helps us make decisions and judgments quickly without having to spend a lot of time researching and analyzing information.
